PWM (Pulse Width Modulation) is a technique to control power delivery by varying the width (duration) of a digital pulse. It’s commonly used for motor speed control, LED dimming, and voltage regulation. By adjusting the duty cycle (ratio of ON time to total cycle time), you can effectively control the average voltage or power delivered to a device. #ElectronicsEducation #electronicsrd #electronics | Electronics Education

Pulse Code Modulation (PCM): A digital modulation technique where an analog signal (green waveform) is sampled at regular intervals using a clock signal (purple waveform), quantized into discrete steps (orange staircase waveform), and encoded into binary. The setup includes waveform generators, a sampling and encoding block, and a 7-segment display to show the binary output in decimal form, visualizing the real-time digital representation of the analog signal. #ElectronicsEducation #electronics
